What's included

Fully end-to-end in Camden.

PD eligibility check

We confirm whether your Camden rear dormer qualifies for Permitted Development — checking volume limits (40m³ terraced, 50m³ semi/detached), Article 4, conservation area and prior extension history.

LDC or planning application

If PD applies, we obtain a Lawful Development Certificate for certainty. If not, we submit full planning with Design & Access Statement to Camden Council.

Dormer design & massing

Full-width flat-roof rear dormer with matching materials, set in from party walls, cheeks clad to match existing roof — the design that Camden Council approves most readily.

Building Regulations package

Part B fire escape (protected staircase, fire doors, smoke alarms), Part K staircase, Part L insulation, Part E acoustic separation.

Structural engineering

Steel ridge beam, purlin supports, dormer framing, floor joist upgrade — chartered engineer sign-off for Building Control.

Party Wall coordination

Most rear dormers in Camden's terraced streets trigger Section 6 Party Wall notices. We draft, serve and coordinate the process.

Which postcode districts around Camden do we cover for rear dormer work?

Every Camden postcode district we draw in, the stock that dominates it and the authority that validates a rear dormer there. Camden fees below are the statutory England rates for 2026, not rear dormer estimates.

PostcodeAreaDominant stockWhat it means for a rear dormer
NW1Camden Town / Regent's ParkVictorian terraces, mansion blocksNW1 straddles a boundary: Camden Town / Regent's Park addresses fall to Camden Council or Westminster City Council, so confirm which authority validates the rear dormer before submitting NW1 drawings.
NW3Hampstead / Belsize ParkGeorgian and Victorian villas, listed buildingsHampstead / Belsize Park sits wholly inside NW3, so Camden Council validates every rear dormer submitted from an NW3 address.
NW5Kentish Town / Gospel OakVictorian terracesKentish Town / Gospel Oak sits wholly inside NW5, so Camden Council validates every rear dormer submitted from an NW5 address.
NW6Kilburn / West Hampstead / Queen's ParkMansion blocks, post-war flatsA rear dormer in Kilburn / West Hampstead / Queen's Park may land with Camden Council or Brent Council — NW6 crosses the boundary, and the NW6 policies map decides it street by street.
W1TFitzroviaGeorgian terraces, Victorian mansion blocksA rear dormer in Fitzrovia may land with Camden Council or Westminster City Council — W1T crosses the boundary, and the W1T policies map decides it street by street.
WC1ABloomsburyVictorian and Edwardian terracesA rear dormer at an WC1A address in Bloomsbury is determined by Camden Council under its own Local Plan policies for Bloomsbury.

How does a rear dormer differ street by street across Camden?

Roof pitch, wall build-up and plot depth change every few Camden streets, and each one changes what a rear dormer can achieve at that address.

How do conservation areas and Article 4 affect a rear dormer in Camden?

Camden conservation designations: there are 40 across Camden Council, Camden Town, Fitzrovia, Hampstead among them. Designation costs a Camden owner the permitted-development route: a rear dormer then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Camden Town is the Camden designation that most often changes a rear dormer design.

What Article 4 removes near Camden: Article 4 removes permitted development for HMO conversions (C3 to C4) across the borough, plus restrictions on basement extensions in 12 conservation areas. Before pricing a rear dormer we check whether the N1C address is inside the mapped area, because Camden Council draws the Camden boundary street by street rather than across the whole of Camden.

Camden below-ground policy: Camden's basement policy (Policy A5) restricts single-storey basements to 50% of garden area; double-storey basements generally refused outside commercial zones. Any rear dormer in Camden that goes below existing foundations triggers two months notice under section 6 of the Party Wall etc. Act 1996, and Camden Council will want the N1C ground and groundwater position set out.

What Camden is built from: Victorian and Edwardian terraces, Georgian townhouses in Bloomsbury and Hampstead, post-war mansion blocks, modern developments in King's Cross. Creative, affluent in Hampstead and Primrose Hill; dense mixed-use around Camden Town and Kings Cross; academic character in Bloomsbury. That mix decides the rear dormer route in Camden more than the postcode does, and it is what a Camden Council case officer reads first. A householder application costs £548 paid to Camden Council direct, with 8 weeks to a decision once validated.

Direct answers to the questions Camden homeowners ask every week about rear dormer drawings.

Do I need planning permission for a rear dormer in Camden?

It depends on your exact address in Camden. Most standard loft conversions qualify as Permitted Development (no planning permission needed) if under 40m³ for terraced or 50m³ for semi-detached, with matching materials and 20cm eaves setback. However Camden has Article 4 Directions that may remove these rights — and flats, conservation areas and listed buildings always require full planning. We confirm permitted development eligibility at the free feasibility visit. Full-width rear dormers are the most common PD loft type in Camden — provided the volume, materials and setback conditions are met. We check every condition before committing to a route.

How much does a rear dormer loft conversion cost in Camden?

A Camden rear dormer has two cost lines: our architectural package (drawings, building regulations and structural calculations, quoted as one fixed figure) and the build, which moves with access, floor area and specification — an en-suite adds plumbing runs and drainage. See our fees.

How much space does a rear dormer add in Camden?

A full-width rear dormer in Camden typically adds 15–25 square metres of habitable floor area — enough for a double bedroom with en-suite, or two single bedrooms. The flat roof gives full standing height across the entire width of the house, unlike a rooflight-only conversion which is constrained by the roof pitch.

Can I have a rear dormer in a conservation area in Camden?

Rear dormers in Camden's conservation areas usually need full planning permission because PD rights are restricted. However, because they face the rear (not the street), Camden Council typically views them more favourably than front dormers or mansards. A well-designed rear dormer with matching materials and sensitive proportions has a strong approval record.

How long does a rear dormer take to build in Camden?

A standard rear dormer in Camden takes 8–12 weeks to build once on site. Our architectural package takes 3–5 weeks from instruction to submission. Building Control approval adds 2–4 weeks. Total timeline from survey to move-in: approximately 4–5 months.
